Description

[Detailed description of the invention] Vehicle body adjustment device and its adjustment method Technical field The present invention relates to an apparatus for adjusting a vehicle body and a method for adjusting a vehicle chassis.

Background technology Such a vehicle chassis adjustment device requires moving the vehicle onto the adjustment stand and attaching it to the hem of the adjustment stand. a method consisting of fixing it in place and then lifting it to the required height position; It is known as. The adjustment operation of the vehicle body is further carried out using split support arms. or its equivalent by applying power to the adjustment tool, and It is accomplished by directing it at the object to be adjusted. Same applicant In Finnish Patent No. 59348 and Finnish Patent No. 53930, Adjustment that allows power to be directed in the required direction on the object being adjusted The device is disclosed. Similarly, the applicant's recent Finnish patent no. In the specification of No. 2265, separate adjustment units can be attached to the adjustment stand. A vehicle body adjustment device that can be adjusted is known. Finnish patent no. 862265 The drawings show the rapid and flexible transmission of power to the object being adjusted as well as the It takes into account the adjustments carried out in the substructure. The purpose of the present invention is to This is an improvement on the partial part drawings of Patent No. 862,265.

In that invention, a rotatable member connected to a slide unit and a receiving notch is provided. The adjustment boom is fixed on the sliding unit which can be fixed in any position. An adjustment unit is provided which is attached to an adjustment stand comprising a semi-circular plate of positions. It has been shown that The adjustment boom can rotate 180 degrees on the vertical axis. Main departure Rotatable adjustment boom located at the end of the adjustment unit as shown is used including a horizontal beam part and a vertical beam part, and the vertical beam part The minutes are rotatably pivoted on a vertical plane, where the horizontal beam Power is transferred from the rotatable vertical beam by movement between the vertical beam section and the vertical beam section. It is further directed onto the object to be arranged on the vehicle body. As shown in the present invention In other words, the adjustment member includes a movable slide unit, which is divided into functional parts. Preferably, a hydraulic cylinder is used in the horizontal direction, preferably in the direction of the central axis X of the adjustment table.

The sliding unit contains a movable box beam, which is located at the center or at the base of the adjustment unit. Oriented by a beam parallel to the X-axis of the frame. The slide unit is It can be fixed at any position with respect to the beam of the base frame of the alignment unit.

Furthermore, the slide unit of the adjustment member is arranged in the Y direction perpendicular to the beam portion in the X direction. contains a beam section for which a split support arm or a direct tool can be fixed.

Therefore, the slide unit can be moved parallel to the center axis X of the adjustment table. Ru. The tool or support arm disposed on the slide unit is further aligned with respect to the X axis. It can move at right angles, which is in the Y-axis direction. Therefore, the adjustment unit of the invention uses an L-shaped adjustment boom that connects to the slide unit and can rotate 180 degrees. Adjustments of the vehicle body undercarriage as well as the vehicle body superstructure can be accomplished easily and quickly. Applies to
